我在我的应用程序中创建更新用户然后 我在Postman和Web App中测试我的应用程序,但创建了不同的结果。 当我在邮递员中尝试此代码时,它可以工作,但Web应用程序不起作用 (ASP.NET CORE 2.0中的代码,使用Angular 5的Web App)
[HttpPut("{id}")]
public async Task<IActionResult> UpdateUser(int id, [FromBody] UserForUpdateDto userDto) {
if(!ModelState.IsValid)
return BadRequest(ModelState);
var currentUserId = int.Parse(User.FindFirst(ClaimTypes.NameIdentifier).Value);
var userFromRepo = await _orgRepo.GetUser(id);
if(userFromRepo == null)
return NotFound($"User not found with id: {id}");
if (currentUserId != userFromRepo.Id)
return Unauthorized();
_mapper.Map<UserForUpdateDto, User>(userDto, userFromRepo);
if (await _orgRepo.SaveAll())
return NoContent();
throw new Exception($"Updating user {id} failed on save");
}
从WebApp中产生错误: “对象引用未设置为对象的实例。”
当我调试应用程序时,似乎该行导致
var currentUserId = int.Parse(User.FindFirst(ClaimTypes.NameIdentifier).Value);
我检查并生成null。
知道用户设置的位置吗?
我的登录控制器:
[HttpPost("login")]
public async Task<IActionResult> Login([FromBody]UserForLoginDto userForLoginDto)
{
var userFromRepo = await _repo.Login(userForLoginDto.Username.ToLower(), userForLoginDto.Password);
if (userFromRepo == null)
return Unauthorized();
// generate token
var tokenHandler = new JwtSecurityTokenHandler();
var key = Encoding.ASCII.GetBytes(_config.GetSection("AppSettings:Token").Value);
var tokenDescriptor = new SecurityTokenDescriptor
{
Subject = new ClaimsIdentity(new Claim[]
{
new Claim(ClaimTypes.NameIdentifier, userFromRepo.Id.ToString()),
new Claim(ClaimTypes.Name, userFromRepo.Username),
new Claim(ClaimTypes.Role, "RegisteredUsers")
}),
Expires = DateTime.Now.AddDays(3),
SigningCredentials = new SigningCredentials(new SymmetricSecurityKey(key),
SecurityAlgorithms.HmacSha512Signature)
};
var token = tokenHandler.CreateToken(tokenDescriptor);
var tokenString = tokenHandler.WriteToken(token);
var user = _mapper.Map<UserForDetailDto>(userFromRepo);
return Ok(new { tokenString, user });
}
答案 0 :(得分:3)
如果api方法包含[Authorize],则会随请求一起发送授权标头。如果没有发送标题,则表示您没有用户。
[HttpPut("{id}")]
[Authorize(AuthenticationSchemes = "Bearer")]
public async Task<IActionResult> UpdateUser(int id, [FromBody] UserForUpdateDto userDto)
{
var sub = User.GetSubjectId(); // Subject Id is the user id
}
